SHIB is an ERC-20 token based on Ethereum, as many other tokens. What is behind success of this coin? Maybe no Venture Capitals, no ICO with big share for it. Homepage of Shiba Inu Says: "From its inception, Shiba Inu has done things differently. Starting with a supply of 1 quadrillion, our founder, Ryoshi, locked 50% in Uniswap, then “burned” the other half to Ethereum co-founder Vitalik Buterin for safekeeping. To help reverse the devastating spread of Covid-19 in India, VB has since utilized SHIB in the largest crypto donation in history, and then actually burned 40% of its total supply to a dead wallet, ensuring our long-term success and stability. In the words of Ryoshi, “Thank you to the woofmeister for enabling true decentralization. Now we truly begin.”"
